“…The remaining two studies [ 20 , 56 ] did not report proportions stratified by sex. In terms of geographical regions, 18 different countries were identified, including 35 studies in Europe [ 20 , 32 , 33 , 35 , 38 - 43 , 46 , 55 - 60 , 65 , 66 , 70 , 74 - 79 , 81 - 83 , 88 , 90 , 94 - 96 , 101 ], 18 in Asia [ 29 , 31 , 34 , 37 , 47 , 48 , 51 - 53 , 61 , 62 , 68 , 87 , 89 , 97 - 100 ], 12 in South America [ 36 , 44 , 45 , 50 , 54 , 67 , 72 , 73 , 80 , 85 , 86 , 91 ], five in North America [ 10 , 49 , 63 , 71 , 93 ], and one in Oceania [ 84 ]. Two studies did not specify the country since it was performed via social media [ 64 , 92 ].…”

Background To date, no previous meta-analysis has determined the overall proportion of orthorexia nervosa symptoms on a global scale. The aim of the present study was 2-fold: first, to establish the overall proportion of orthorexia nervosa symptoms on a global scale, assessed with the ORTO-15 questionnaire; and second, to determine the role of sex, type of population, mean age, body mass index, and the temporal trend in relation to orthorexia nervosa symptoms. Methods Four databases were searched (PubMed, Scopus, Web of Science, and Cochrane Database of Systematic Reviews) with date limits from January 2005 to June 2023. Studies assessing the proportion of orthorexia nervosa assessed using the ORTO-15 questionnaire with a cutoff of <35 or <40 points were included in this review. Results The overall proportion of orthorexia nervosa symptoms (using the cutoff <35 points) was 27.5% (95% confidence interval (CI) = 23.5-31.6, I 2 = 97.0%). In addition, no significant differences were observed between females (34.6%, 95% CI = 29.5-39.8, I 2 = 96.1%) and males (32.1%, 95% CI = 26.5-38.1, I 2 = 93.1%). According to the type of population, the highest overall proportion was found in people focused on sports performance or body composition (34.5%, 95% CI = 23.1-47.0, I 2 = 98.0%). Notwithstanding, caution should be exercised in interpreting this result, as reverse causality could be a potential pitfall in this relationship. Conclusions We found that approximately three out of 10 study participants showed orthorexia nervosa symptoms according to the ORTO-15 tool. This overall proportion was higher in those participants who were athletes or fitness practitioners. Over the years, the proportion of orthorexia nervosa symptoms seems to be increasing. These high percentages and their increase are worrisome from a public health perspective and highlight the need to develop psychometric instruments to aid in clinical diagnosis and treatment efficacy.
